<p class="docText">There are two types of web pages: static<a name="IDX-CHP-1-0009"></a> 
 and dynamic.<a name="IDX-CHP-1-0010"></a> 
 A static site provides hyperlinked text and perhaps a login screen, but beyond that, it doesn't require additional participation from the user. <a class="docLink" target="_blank" href="http://www.startribune.com">http://www.startribune.com</a> is an example of a static site, except that you do have to register to view articles. <a class="docLink" target="_blank" href="http://www.amazon.com">http://www.amazon.com</a> is an example of a dynamic web site, because your ordering data is logged, and Amazon offers recommendations based on your purchasing history when you access their page. In other words, <span class="docEmphasis">dynamic</span> means that the user interacts more with the web site, beyond just reading pages, and the web site responds accordingly.</p>
<p class="docText">Creating dynamic web pageseven a few years agomeant writing a lot of code in the C or Perl languages, and then calling and executing those programs through a process called a Common Gateway Interface (CGI). Having to create executable files doesn't sound like much fun, and neither does learning a whole new complicated language. Well, thankfully, PHP and MySQL make creating dynamic web sites simpler, easier, and faster.</p>
